LM5050MK-1 Description

Short technical summary and product information.

The Texas Instruments LM5050MK-1 is an active ORing FET controller designed for robust power management solutions. It supports a wide input voltage range from 1V to 75V, with a 100V transient capability, making it suitable for demanding applications.

 

Key electrical characteristics include a maximum current handling of 250A and a typical quiescent current of 0.4mA. The device features a charge pump gate driver for external N-channel MOSFETs, a fast 50ns response time to current reversal, and a minimum VDS clamp for faster turnoff. The operating temperature range is -40°C to 125°C.

 

This controller is available in a compact SOT-23-6 (also referred to as SOT-6 or Thin SOT-23-6) surface-mount package with dimensions of 8.12 mm² (2.9 mm × 2.8 mm). It offers features such as AUX input, linear control, reverse current blocking, and reverse polarity protection.

 

The LM5050MK-1 is suitable for applications requiring reliable power path management, such as redundant power supplies, high-side ORing, and eFuses.
